Overview of Hub
Management
Hubs themselves are rarely the cause of problems on the network.
However, since hubs are the center point for many devices on the
network, it’s a good place to start looking for problems.
There are four categories of management tasks:
Configuring the hub or stack of hubs. This includes setting the IP
configuration, naming the hubs, and disabling individual ports.
Monitoring traffic. This helps to plan network expansion or make
segmenting decisions.
Finding malfunctioning devices such as LAN adapters in PCs.
Finding wiring problems between an attached device and the hub.
There are several methods for managing hubs. You can use any
combination.
Manage with the onboard LCD or Console Manager. This method
works best for initial setup or when the network goes down and
you can’t access the hub with an SNMP application.
Manage with Intel Device View for Web or LANDesk® Network
Manager. These SNMP applications are tailored for Intel products
and show a graphical representation of the hub.
Manage with any other SNMP-compliant application. If you
already use an SNMP application, you can manage hubs by
compiling the hub’s MIB files into that application. File locations
are listed on page 51.

Managing multiple hubs
To manage multiple hubs, you must stack them using Intel Cascade
Cables.

Hub numbering
Once connected with Intel Cascade Cables, the Management Module
numbers hubs from top to bottom, regardless of the placement of the
Management Module.

Collision domain assignments
All hubs running at the same speed in the stack belong to the same
collision domain. In the example below, all devices (PCs, print
servers, and so on) connected to hubs 1 and 2 share 100 Mbps of
bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of
bandwidth.
